Circuit Protection Electronics attenuation EMI protectionQUELL EESeal+ EMI filter inserts deliver improved attenuation and frequency mitigation. The inserts are easily and quickly inserted into standard connectors in seconds without the need for any special tooling or soldering, forming an effective EMI filter and maintaining the environmental seal. Customized samples are available at very short lead times. Products use firm’s patented EESeal+ technology which uses EMC filter components embedded into a silicone rubber insert that matches the size, shape and pin configuration of the connector to be filtered. Transient suppressors can also be included. Users can specify which filter elements are required for each pin, allowing for the creation of a completely custom filter insert with widely varying capacitor values, shorts and opens as desired.
